Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The following will further describe the present application in detail Figures 1-5 in conjunction with the attached drawings.

[0024] An embodiment of the present application discloses a roadbed compaction device. Refer to Figures 1-5 , a roadbed compaction device, including a rammer pump body 1. The rammer pump body 1 includes a pressing plate 101. A vertical plate 103 is fixedly connected to the front side of the pressing plate 101. A connecting member 102 is fixedly connected to the front side of the vertical plate 103. A high-frequency compaction mechanism 2 is arranged on the top of the pressing plate 101. Fixed mechanisms 3 are arranged on both sides of the high-frequency compaction mechanism 2;

[0025] The high-frequency compaction mechanism 2 includes a fixed box 201. The bottom of the fixed box 201 is fixedly connected to the top of the pressing plate 101. A first connecting seat 202 is fixedly connected to the top of the inner cavity of the fixed box 201. A first rotating shaft 203 is fixedly connected to the inner cavity of the first connecting seat 202. A long rod 204 is rotatably connected to the surface of the first rotating shaft 203.

A fixed sleeve 207 is fixedly connected to the bottom of the second connecting seat 205. A double-shaft motor 208 is fixedly connected to the inner cavity of the fixed sleeve 207. A duck tongue plate 209 is fixedly connected to the output end of the double-shaft motor 208.

[0026] Refer to Figure 2 , third connecting seats 210 are fixedly connected to the front side and the back side of the fixed sleeve 207 respectively. A first rotating block 212 is rotatably connected to the inner cavity of the third connecting seat 210. One end of the first rotating block 212 is fixedly connected to a spring 213. The other end of the spring 213 is fixedly connected to a second rotating block 214. The surface of the second rotating block 214 is rotatably connected to a fourth connecting seat 216. One fixed connection of the fourth connecting seat 216 is to the inner wall of the fixed box 201. Through the arrangement of the spring 213, when the duck tongue plate 209 rotates, centrifugal force will be generated, driving the fixed sleeve 207 to vibrate up, down, left and right in the inner cavity of the fixed box 201. At this time, the spring 213 buffers the energy generated during the vibration of the fixed sleeve 207, and at the same time limits the position of the fixed sleeve 207 to prevent the fixed sleeve 207 from rotating irregularly around the first rotating shaft 203;

[0027] Refer to Figure 2, a third rotating shaft 211 is fixedly connected to the inner cavity of the third connecting seat 210. The inner cavity of the first rotating block 212 is rotatably connected to the surface of the third rotating shaft 211. A fourth rotating shaft 215 is fixedly connected to the inner cavity of the fourth connecting seat 216. The inner cavity of the second rotating block 214 is rotatably connected to the surface of the fourth rotating shaft 215. Through the arrangement of the third rotating shaft 211, the position of the first rotating block 212 is supported, making the first rotating block 212 more stable during rotation and preventing the first rotating block 212 from falling off from the inside of the third connecting seat 210;

[0028] Refer to Figure 4 and Figure 5 , the fixing mechanism 3 includes a square block 309, an electric push rod 308 and a gear 304. The bottom of the square block 309 is fixedly connected to the top of the pressing plate 101. The number of the square blocks 309 is four. A sliding plate 301 is fixedly connected to the top of the square block 309. A counterweight 6 is placed on the top of the sliding plate 301. Tooth plates 303 are movably connected to the left and right sides of the sliding plate 301. A driving block 306 is fixedly connected to the top of the tooth plate 303. The top of the driving block 306 is in contact with the top of the sliding plate 301. A clamping plate 307 is fixedly connected to the inner side of the driving block 306. The inner side of the clamping plate 307 is in close contact with the surface of the counterweight 6. The electric push rod 308 is fixedly connected to the front side of the vertical plate 103. The number of the electric push rods 308 is two. The output end of the electric push rod 308 penetrates to the back side of the vertical plate 103 and is fixedly connected to one side of the driving block 306. The gear 304 is rotatably connected to the bottom of the sliding plate 301. The surface of the gear 304 is meshed with the surface of the tooth plate 303. Through the arrangement of the gear 304, two tooth plates 303 can be driven to move simultaneously, and then the driving block 306 can be driven to move, so as to fix the position of the counterweight 6. Also, through the arrangement of the square block 309, the position of the sliding plate 301 is raised, preventing the bottom of the sliding plate 301 from contacting the top of the pressing plate 101 and causing the situation that the tooth plate 303 cannot move;

[0029] Refer to Figure 3 and Figure 4 , two sliders 302 are slidably connected to the inner cavity of the sliding plate 301. One side of each slider 302 is fixedly connected to one side of the tooth plate 303. Through the arrangement of the sliders 302, the tooth plate 303 can move more stably, effectively preventing the tooth plate 303 from shaking during movement;

[0030] Refer to Figure 5, a short rod 305 is rotatably connected to the inner cavity of the gear 304, and the top of the short rod 305 is fixedly connected to the bottom of the sliding plate 301. Through the arrangement of the short rod 305, the position of the gear 304 is supported, making the rotation of the gear 304 more stable and preventing the gear 304 from disengaging from the toothed plate 303 during rotation, thus avoiding the occurrence of a situation where fixation cannot be achieved;

[0031] Refer to Figure 3 , a vertical rod 4 is fixedly connected to the top of the pressing plate 101. The number of the vertical rods 4 is eight. A guiding column 5 is fixedly connected to the inner side of the vertical rod 4. The inner cavity of the clamping plate 307 is movably connected to the surface of the guiding column 5. Through the arrangement of the vertical rod 4, the position of the guiding column 5 is supported, preventing the guiding column 5 from falling off from the inside of the vertical rod 4. Also, through the arrangement of the guiding column 5, a guiding effect is exerted on the clamping plate 307, making the movement of the clamping plate 307 more stable and avoiding the occurrence of a jamming situation caused by the unstable movement of the clamping plate 307.

[0032] Working principle: When in use, first connect the connecting piece 102 to the power machine through the pin piece, and then start the electric push rod 308. The output end of the electric push rod 308 pushes the driving block 306 to move. The movement of the driving block 306 drives the clamping plate 307 to move, and the movement of the driving block 306 will drive the toothed plate 303 to move. The movement of the toothed plate 303 drives the gear 304 to rotate. The rotation of the gear 304 drives another toothed plate 303 to move, thereby enabling the two driving blocks 306 to move simultaneously, and then clamping the counterweight 6. Through the arrangement of the counterweight 6, the weight of the pressing plate 101 is increased, making the compaction of the roadbed more firm. At this time, start the double-shaft motor 208. The double-shaft motor 208 drives the tongue plate 209 to rotate at a high speed. Through the high-speed rotation of the tongue plate 209, the fixed sleeve 207 is driven to vibrate at a high frequency. The vibration of the fixed sleeve 207 causes it to move rapidly around the first rotating shaft 203, and then transmits the force to the fixed box 201. Since the top of the pressing plate 101 is directly fixedly connected to the bottom of the fixed box 201, the force of high-frequency vibration is transmitted to the pressing plate 101. Through the high-frequency rotation of the tongue plate 209, the ground to be constructed is quickly impacted by the pressing plate 101, and at this time, the compaction work of the construction ground is completed.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
